Photocatalytic degradation of waste pollutants using TiO2is a promising technology. Recently, the use of bentonite for the removal of organic pollutants was widely studied because of large specific surface areas. Studies have shown that TiO2supported on bentonite, or TiO2/bentonite composite, exhibits bifunctionality of adsorption and photo catalysis in synergism. This paperpresents a literature review of the preparation and modification techniques of bentonite/TiO2composite photocatalyst, and their characteristics. The review will also focus on the current researches on the degradation of water organic pollutants by using bentonite/TiO2composite photocatalyst and its key influencing factors.

Due to its outstanding photo-catalysis properties, low-dimensional V2O5 has many important applications in lithium ion batteries, supercapacitors, electrochromic devices, photocatalysts, sensors, et al. As good photocatalysts for organic pollutants, some key issues of photocatalysts are charge generation, separation, transfer of nanocomposites under irradiation of visible light. To improve their important properties and pave the effective conductive channels for charge transfer and separation, low-dimensional V2O5/graphene nanoribbons nanocomposites were prepared. The emphasis is put on adsorption response to VOC of nanocomposite based on the QCM (quartz crystal microbalance) device. In order to investigate the mechanism of charge-generated by visible light, the photoconductivity response to visible light and 808 nm laser with low-power were studied based on interdigital electrodes of Au on flexible PET (polyethylene terephthalate) film substrate. Some good results were obtained. This illustrates that this nanocomposite can easily produce the charge-generate with visible light and 808 nm laser with low-power, avoiding the recombination of charge-generate by light. It would be good applications in remove the organic pollutants with photocatalysis effects.
